FAQ

Is goldprice.dev an alternative to Twelve Data for commodity pricing?

Yes, for gold and silver. goldprice.dev covers gold, silver and copper spot on every plan, dealer prices from Basic, and full daily history from Plus. Twelve Data is a multi-asset generalist covering stocks, forex, crypto, indices, ETFs, and commodities; gold and silver surface under its /commodities endpoint as XAU/USD and XAG/USD. Pick Twelve Data if metals are one asset of many in a portfolio product. Pick goldprice.dev if metals are the primary use case and per-source transparency and dealer prices matter.

How does Twelve Data's credit-based pricing compare to goldprice.dev?

Twelve Data meters API credits per minute: 8 credits/min on Free (with an 800 calls/day hard cap), 377 credits/min on Grow, 1,597 credits/min on Pro, 10,946 credits/min on Ultra. An endpoint call can cost 1 to 10+ credits depending on the endpoint and parameters. goldprice.dev meters monthly calls at the tier's flat quota with a per-minute rate limit: Free 5,000 calls/month at 10 req/min, Basic 100,000 at 60/min, Plus 300,000 at 120/min, Pro 1,000,000 at 300/min. For metals-only workloads at predictable volumes, goldprice.dev's flat-call model is easier to budget; for multi-asset portfolio apps hitting dozens of endpoints per request, Twelve Data's credit pooling is more flexible.

Does Twelve Data cover futures settlement for metals?

Twelve Data's commodities endpoint lists XAU/USD (Gold Spot) and XAG/USD (Silver Spot). Its public documentation does not call out distinct futures settlement symbols (GC for gold, SI for silver, HG for copper) at the commodities-endpoint level. No new goldprice.dev plan includes futures or settlements. If your product resolves against settlement rather than spot, confirm coverage with Twelve Data's support before committing.

Which API has MCP (Model Context Protocol) support?

goldprice.dev ships a native MCP server on every plan, including Free. Twelve Data has no MCP offering as of 2026-04-25. If you are wiring commodity data into Claude, Cursor, or a custom agent, goldprice.dev exposes nine MCP tools over stdio; Twelve Data integrations require REST-wrapper code.

Which API exposes a forward view and cross-source divergence for gold?

No new goldprice.dev plan includes futures, settlements or their forward curves. Twelve Data returns spot prices without a forward-view or cross-source divergence overlay.

Which API should I pick for a multi-asset portfolio product?

Twelve Data. If gold is one asset alongside stocks, ETFs, forex, indices, and crypto in a single portfolio or analytics tool, Twelve Data's broad catalog under one API key and credit system fits the shape. goldprice.dev only covers gold, silver, and copper. Outside metals, goldprice.dev is not the right API.

How is per-source provenance disclosed in each API's responses?

goldprice.dev returns sources[] (via ?include=sources) with source identifiers and timestamps: one 'Live spot' source per spot row, USD spot × live exchangerate.dev FX for non-USD gold. Twelve Data returns a single value per endpoint call without per-source attribution. If downstream redistribution or compliance requires per-source identifiers and timestamps, goldprice.dev exposes it with ?include=sources.

Does Twelve Data offer WebSocket streaming?

Yes. Twelve Data supports WebSocket with a separate pool of WS credits per tier (trial pool on Free + Grow, 1,500 WS credits/min on Pro, 10,000 WS credits/min on Ultra). goldprice.dev streams XAU, XAG and HG on Plus ($39/mo), with 1 SSE or WebSocket connection. Pro allows 5 SSE and 5 WebSocket connections, including streamed dealer prices. For non-metals assets (stocks, forex, crypto), Twelve Data's WebSocket coverage is broader.

Does Twelve Data offer per-country gold dealer prices?

No. goldprice.dev Basic ($19+) covers live dealer sell and buyback quotes with premium-over-spot across selected countries. Twelve Data's /commodities endpoint returns XAU/USD and XAG/USD spot with no per-country dealer feed.
